To all whom it may concern} F Be it known thatl, EDWIN S..-VorEY, a citizen of the United States, and a resident'of the boroughof Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Music-Rollcouplings movablymounted on the s afts to 5.

accommodate rolls or" different lengths or rollshaving different engaging members, which may thus be used interchangeably on the same instrument.

' Under the present invention one' or more of the couplings without being detached from the ends of the, shafts whennot in use partly in front. elevation, partly in vertical section, shows my device as engageable with a hollow-ended roll, the coupling and the roll being slightly separated for clearness of illustration. Fig. 2 is an endview of the couplingin other words, aview on the plane 2 2, Fig. 1. Fig. 3 is a front elevation of the coupling as'about to be engaged with a roll provvided with the ordinary non-circularpm.

Fig. 4 is a like view of the device with the movable member of the coupling in its non" operative position. Fig. 5 is a transverse section on the'plane 5 5, Fig. 4, the scale being enlarged. Fig. 6 is a front elevation of a modified form of my device. Fig. 7 is an end elevation of the device shown in Fig. 6. Fig.

8 is a front elevation ofjthe same device with the movable parts of the coupling turned to their non-operative position.

Referring tojFigs. 1 to 5 of the drawings, 1 designates a shaft which in practice is mounted ona musical instrument or player for the sup ortof a music roll; T

e particular sha t-sho'wn' is the one'located at the right end of. the roll and in p'rolvided with means for rotating. the roll'to rewind the music- "sh'eet; thereon after playing: rAs the mou'nt ingjof'the shafts and the means for rotating the driving-shaft are well known, I have not Specification of Letters Patient. 7 application filed September 20, 1905- Scriel No. 279,285;

encumbered the drawings with them. At the end of the shaft 1, as shown, is a coupling member 11, having a bore 12, the wall of which is slotted at 13. Projecting laterally from the member 11 is a lug 14, shown as bifurcate and forming a hinge member for cooperating with ahinge-lug 21 on a coupling 2. As a means. of holding the coupling member 2 in either its operative or its non-operative position I introduce frictional resistance to the adjusting movement of the member'preferably-by making the pintle 15 of the hinge in the form of a screw engaging into one side of the lug 14 and carrying a thrust-sprin 16, which forces a washer 17 against the si e of the hinge member 21. (See Fig. 5.) The ccgii'pling member'2 has an approximately cyli ric ortion 22, having a bore 23, and slots 24 simi ar to the bore 12 and slots 13 in the couplin member 11. It is also formed with a latera 1 -extending flange-25,11aving a forwardly-extending portion '26, bounded by arc-shaped recesses 27, in one of which is a pin 28. Arcshaped rims 29 form the periphery of the flanged portions 25.

The operation of the device will be readily understood by reference to the drawings.

Fig. l -shows the coupling member 2 in its operative position in'which'it is ofcourse in t is shown as about to be engaged with the i101: low end of a music-roll 3. The music-roll here shown has a hollow end, in this case formed by'a sleeve 31. The portion 26 of the flange 25 enters this hollow end of the roll 3 and serves to center and support it. The roll 3, as shown, has a head 32 on the sleeve 31 in which is cut a notch or recess 33, in which notch the pin or tooth 28 engages. The r0113 is also centered and supported by the engagement of the .bead 32 within the outer rim 29 of the flange 25 of the coupling. It is evident that either the'enga'ging portion 26, entering the hollow end of the roll, or the rim portion 29, embracing the head 32, would alone sufiice to hold the roll in position. V

' Fig.- 3 shows the coupling member 2 as being engaged with a winged in 41 of a music-roll 4', the pin entering t e bore 23 and geth'er forming a clutch. v it In Fig. 5'of the drawings the couplingmem her 2 is shown as turned to its non-operative position, leaving the clutch member 11 at the end of the shaft 1 ready for engagement with a pin 41 of a r0114, or rather of a roll of similar pattern but of greater length.

The modified form of my device shown Figs. 6, 7, and 8 of the drawingsisfsimilar in operation and function to that already described. The shaft 101 has a coupling member 111,formed, as befoiewith abore 112 and slots 113, adapted to engage with a winged pin, as 41, Fig.3. In this case, however, the coupling member 111 has two oppositely-disposed bifurcate lugs 114, each carrying a pintle 115 andforming a hinge member for a part of a coupling member 102. Obviously these hinges may be provided with a suitable holding or friction devicee. 9., such as is shown in Fig. 4. One art of the coupling member 102 is provided as before, with an approximately cylindric portion 122, having" a bore 128 and slots 124 in its Wall. Both parts of the member 102 have flanges 125, formed with centering ortions 126, areshaped-recesses 127, an rim portions .129. In the recess 127 in one of the parts is a pin .01 tooth 128. It is obvious that when the coupling member 102 is in longitudinal alinement with the shaft 101, as shown in Fig. 6,

it is 'adaptedto engage either roll 3 0114, as

above described, and that when the parts of the .member' are turned back to the position shown-"in Fig. 8 the coupling member 111 is, as before, ready for engagement with a pin 41. By making the coupling member 102 in havingat its free end a coup engaging and rotating a musicroll, and atwo parts,'which-fold back on opposite sides of the shaft, and'especially by making them of unequal segments, as shown, the tendency to throw the shaft is obviated or lessened, while at the same time a larger portion of the circumference of the hollow end 31 of the roll or of the periphery of'the bead 32 on the roll is engaged.

It is clear that modifications other than those shown may be made in the form of the device without departing from m invention. In copending applications filled October 13, 1905, Serial Nos. 282,660 and 282,661, re spectively, I have shown a hollow-end musicroll provided with a sleeve having an outturned bead in which is cut a notch or recess and a coupling device having a centering or engaging-member and a flange provided with a tooth for engaging in such notch and have claimed the same generically. It is obvious that I do not herein'claim anything claimed in either of those applications.
